To a/ZZ whom it may concern:

Be it known that I, PA'rRlcKJ. OBRIEN, a of Great Britain, and a resident of the city of Mobile, Newfoundland, have invented certain new and useful Im rovements in vSash Raising and Locking evices", 'of which the followlngis a specification.

My invention, relatesto certain new andv useful improvements in -devices for counterbalancing and raisin window-sashes and the ocling the sash in any like and means for position desired. l

Primarily my invention has for its object to provide a device of this character 0i' a very simple and effective construction which can be easily and cheaply manufactured and which will readily and `effectively serve its intended purposes.

Generically my invention embodies aV slotted plate adapted to be attached tothe window-frame and containing lock-receiving spaced apart, a device secured to the window ior projecting through the slotted plate, and a spring secured to said window-attached devices and to a member on the Window-frame for lifting the window at times. v

My invention also includes an im roved lock for cooperating with the lifting evices for holding the window in its ad'usted position and comprises a-sp'ringawl carried by the window and projectin eyond the side -apertures of the window-'frame late. c

With other o jects in view than have been heretofore enumerated the' invention also comprises certain novel construction, combiznatlon, and arrangement fof parts, all of which will be first described in detail and then be specifically pointed out in the alphad to te frame bein shown in section to more clearly invention.

Fig. 10 is a detail section of a portion of the window and frame, illustrating the manner in 'which the latch member engages the apertured portion in the window-frame. l

Referrin now to the accompanying' drawin which like numerals of reference indicate like parts in all ofthe, figures, l designates the window, and 2. the frame, all of which may be Incarr-yin out my invention I provide a I secure to the window-frame y screws 3a at a suitable distance alongside of the frame, and the plate 3 is provided with an elongatedslot 3", terminating at one end in a right-angled extension 3P, which runs VThe window-frame is cut out to corres ond with the slot 3" 3 and is of the usual ho low-blpx type.

Within the frame, on each side of the of the ordinary construction.

dow, I locate a spring 4, one end 4 of which rejecting through. the slot 3P`and formed wit aplate 5, which is ada ted to be secured in asuitable countersunli portion 1 on the side of the window 1 by screws 6, as shown, the stud-bolt 5 having a s ike portion 5b to enter the windowvhe other end 4b of the lower springs is secured to a similarl -forme bolt 7, secured to the win shown.

The plates 3 have suitably-spaced latchreceiving apertures 3d to coperate with the latch 8, carried by the window, and the latch edge plate 8F and a key-plate 8b, formed together and secured to the window-sash in suitable mortises by screws 9, as shown. The latch 8 also comprises a latch member 10, having,a spring-arm 10a secured to the plate 8, as at 10", an a latch-head 10, which proj ectsthrough anaperture 8* in the plate 8F and is adapted to enter the a ertures 3d of the plate 3, as will be clearly un erstood by reference to the drawings. The latch stud- .memberplO lalso has a heel portion 10d, pro- Sf and y means of which t e latch can be air of ow-frame, as

on each side thereof, and the are so arranged as to aord an. easy opera- I the'WindoW-frame and guide thepins51and means entirely W released I may tion against the Withdrawn from the apertures 3d to ermit the springs 4 to aid in raising the win 0W, as will be presently more fully explained.

By providing the slot 3, when the Windows are closed and the beading 2a .removed from. the window-frame the Windows 1. can be swung out of the frame When it is desired. to remove the Windows.

In practice I provide a late 3 at each side of the lower and u per Win oW-sashes and two springs 4 likewise ocated for each Window, onef plates and springs tion of opening tbe Windows.'

By reference to Fig. 2 of the drawings it Will be seen the s rings for the upper Win-I dow 4 are norma ly compressed when .the Window is closed, While those for the lower Window' are normally Aexpanded When the' lower window is closed, andthe latch devices 8 serve to hold the Window in its adjusted; position against the tension of the sprm s 4.' It should be understood that theWin oW- frame is provided with suitable grooves to receive the springs 4.

It will be also noticed that by providing the latch with the spring portion 1()a after' the latch has been released from the aper' tures 3d by releasing the o erators pressurev on the latch the same will eforced against: the plate 3 and. serve as a friction-retardingv means to prevent the springs 4 releasing the Windows too rapidly. e'

Instead of usm the springs 4 as a raising lien the latch membersare springs 4 only slightly more than counterbalance the weight of thus aid the manual operation ofvopening the Windows. l

The slotted blades 3 serve a twofold func-"- tion: First, they protect the .Woodwork of keepthemfrommarring or chipping' the grooved portion of the window-frame casing,- and, secondl .,S they serve, in conjunction Withgth'e latch, .to hold the Windowposif tension of the springs.
